The blade design process starts with a 'best guess' compromise between aerodynamic and structural efficiency. The choice of materials and manufacturing process will also have an influence on how thin hence aerodynamically ideal the blade can be built. For instance, prepreg carbon fibre is stiffer and stronger than infused glass fibre. The chosen aerodynamic shape gives rise to loads, which are fed into the structural design. Problems identified at this stage can then be used to modify the shape if necessary and recalculate the aerodynamic performance.
